How to remove the CPS?

I'm getting a new CPS today, and if it doesn't rain I will be replacing it. I notice that the oil filter is in the way and I might have to remove the filter before I can get access to the CPS, but I'm not sure. Does it require the oil filter to be removed first? If you have any hints & tips on replacing the CPS please let me know.

Thanks,
Quang

I think I took mine off when changing the CPS but not sure if you HAVE to. It just seemed easier with it out of the way.

Why did you change yours? Just curious. Was it because of a hard start or sudden stall problem?

No, mine was dead. It turned out that the problem was a bad coil.

I just picked up my CPS, but have to wait until tomorrow to install it. I hope this is the last item I have to change to make it run again, and hope my coil is okay.

How did you find that your coil was bad?

I don't think my method will help you because I have a few 124s and I just swapped coils with my wife's car and found that it was dead. Don't ask me why I didn't do that before replacing the CPS (!)

I attempted to remove my old CPS today without luck. I have the correct bit connected to a u-joint with a 12-inch 1/4" extension bar. The hex screw didn't want to turn. I was afraid that I'd strip the screw's hole. I sprayed some super lubricant hope it'll come out tomorrow.

There's not too much room in there. How did you manage to take yours out? What tools did you use?
